image overlaps

[ebocher]

Dear list,

I want to multiply  two images but without the same x and y origin. I use
the calibration method but it seem that x and y origin are not taken into
account.
I put a figure in attach file.

Is there a possibility to do it with imageJ ?

Thanks

R1.

You can resize the canvas so the 2nd image is offset to the 1st one (or
viceversa) and fill the offset space with 1 so when multiplied, the result is
unchanged.

Hi,

I want to program this. Do you have an example ?
Thanks.

... or simply re-sample one image, shifting the images so that they  
formally overlap (lots of ImageJ examples out there; try my trivial  
Shift_Image plugin if the rotation and scale doesn't have to be  
corrected for: http://www.astro.physik.uni-goettingen.de/~hessman/

Or something like this:

run("Clown (14K)");
run("8-bit");
run("Duplicate...", "title=clown-1.jpg");
run("Select All");
run("Fill");
run("Subtract...", "value=254");
setPasteMode("Copy");
selectWindow("clown.jpg");
run("Copy");
selectWindow("clown-1.jpg");
run("Select None");
makeRectangle(98, 41, 320, 200);
run("Paste");
run("Select None");
imageCalculator("Multiply create", "clown.jpg","clown-1.jpg");

Cheers,

The turboreg plugin from http://bigwww.epfl.ch/thevenaz/turboreg/ might
be helpful,too.
